Replicating Objects: Molecular Assemblers vs. Physics

  • Thread starter Thread starter hammertime
  • Start date Start date
AI Thread Summary
Replicating macroscopic objects atom-for-atom raises significant challenges, primarily due to the limitations imposed by known physical laws. Molecular assemblers are considered a potential solution, but their feasibility is questioned due to numerous technical hurdles. Previous discussions highlight that alternative methods may not circumvent these obstacles. The consensus suggests that the complexities of replication cannot be easily resolved by simply changing the approach. Achieving accurate replication remains a daunting task within the current understanding of physics.

So I've started a few threads here and there about teleportation and molecular assemblers, but I think that what I'm really curious about is the idea of essentially replicating, atom-for-atom, a macroscopic object. It seems to me that molecular assemblers would be the best way to do that, but is there any other method that could be used that doesn't violate any known physical laws?

In your other thread about molecular assemblers, ryan has some excellent answers on this topic but you appear to be ignoring them. He has highlighted many of the huge hurdles in the way of accomplishing a replica and they won't go away by using a different 'method'.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
